SMART WIRELESS APPLICATIONS
Plastics Manufacturer Improves Energy Costs
With Wireless Flowmeters
BENEFITS
•Improves energy cost management
•Reduced operation and maintenance costs
•Increased the safety of plant personnel
CHALLENGE
This plastics manufacturer had challenges trying to keep their process
units accountable for the steam usage within the plant. The company
needed to better understand their steam usage to know if there were
leaks or other waste in their system.
The plastics manufacturer needed to make six flow measurements on
steam distribution lines that were located throughout their facility.
Unreliable insertion vortex and turbine meters were not providing
reliable steam flow measurement and constantly required maintenance.
These meters would frequently fail and needed to be replaced. The
measurement points are located outside in a cold environment, requiring
the manufacturer to consider the use of heat tracing or other measures
to safeguard the measurement instrument from freezing.
Not having reliable steam flow measurement constrained their ability
to effectively manage their energy costs by process unit. Furthermore,
the unreliable measurement instruments increased maintenance
problems that required frequent replacement of flowmeters at high
installation costs. Replacing their flowmeters required maintenance
personnel to climb scaffolding to reach the installations in icy and
dangerous locations.
SOLUTION
The plastics manufacturer purchased four 3051SFC Compact Orifice
Wireless Flowmeters and two 3051SFC Annubar Wireless Flowmeters.
The wireless technology enabled them to install the flowmeters without
the need for wiring. They utilized new top mounting installation
recommendations for DP flowmeters in steam service. By direct
mounting the transmitter above the pipe, the installation eliminated
impulse lines and utilized the heat of the process to safeguard the
installation from freezing. This eliminated the need of costly heat tracing.

RESULTS
Utilizing reliable wireless flowmeter technology enabled the plastics
manufacturer to understand their steam usage in the plant. In addition,
they saved $40K in wiring costs by using wireless technology and
eliminated the frequent maintenance and replacement of the unreliable
flowmeters. They were also able to achieve a safer work environment
for their maintenance personnel as they were not required to frequently
troubleshoot failures in hazardous conditions.
